Hidden Secret Codes Every Android Owner Should Know

There have always been hidden messages and codes in software for those who know to look; a secret password or a combination of gestures that can unlock a secret command. The reason these exist is because programmers and software designers are no different than artists and storytellers and filmmakers when it comes to ‘easter eggs’. You’ve heard of these hidden items in Disney and Marvel Movies and Video Games and they are a way for the artist to call out to those “esoteric” observers who can spot that which the casual art lover can’t. In software, some trapdoors are purposely left open for people to discover hidden features on their own.
